A recent study indicates that individuals who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain shed pounds much more quickly than those who end conventional diet and exercise plans.
Findings released in a leading health publication demonstrates that while obese individuals frequently drop substantial amounts of their total mass while using the jabs, the weight comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"People purchasing such treatments must be aware of the danger of rapid rebound weight gain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to starting weight in about one and a half years.
Comparing Therapies
The analysis, which reviewed dozens of trials involving thousands of patients, compared the outcomes of GLP-1 agonists with other pills.
The team point out that people who lose weight through diet and exercise typically have a slower weight regain—around 0.1 kg a month—once they finish.
Understanding the Quick Rebound
Doctors suggest the mode of action of the drugs explains the amplified rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication leads to hunger is uncontrolled, making binge eating a significant risk."
An Ongoing Disease?
The NHS suggest the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
A number of clinicians say that, due to the likelihood of relapse, the treatment might need to be ongoing.
This view is reinforced by drug manufacturers, who say that the results "highlight the chronic nature of excess weight," akin to managing conditions like diabetes.
User Accounts
People who have come off the medication report a intense resurgence of appetite.
"I experienced a trigger activating and you're instantly extremely hungry," recalled a patient.
This difficulty is exacerbated if individuals have not adopted sustainable lifestyle or habit changes during treatment.
Growing Adoption
Survey data indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is greater among females compared to men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, experts emphasize that while these medications are powerful tools for weight loss, they are not a magic cure and maintained weight loss hinges on integrated lifestyle changes.
